public interface PreparedStatement extends Statement
An object that represents a precompiled SQL statement.A SQL statement is precompiled and stored in a
PreparedStatement
object. This object can then be used to efficiently execute this statement multiple times.Note: The setter methods (
setShort
,setString
, and so on) for setting IN parameter values must specify types that are compatible with the defined SQL type of the input parameter. For instance, if the IN parameter has SQL typeINTEGER
, then the methodsetInt
should be used.If arbitrary parameter type conversions are required, the method
setObject
should be used with a target SQL type.In the following example of setting a parameter,
con
represents an active connection:PreparedStatement pstmt = con.prepareStatement("UPDATE EMPLOYEES SET SALARY = ? WHERE ID = ?"); pstmt.setBigDecimal(1, 153833.00) pstmt.setInt(2, 110592)

-
clearParameters
void clearParameters() throws SQLException
Clears the current parameter values immediately.In general, parameter values remain in force for repeated use of a statement. Setting a parameter value automatically clears its previous value. However, in some cases it is useful to immediately release the resources used by the current parameter values; this can be done by calling the method
clearParameters
.- Throws:
SQLException
- if a database access error occurs or this method is called on a closedPreparedStatement
-
setObject
void setObject(int parameterIndex, Object x, int targetSqlType) throws SQLException
Sets the value of the designated parameter with the given object. This method is like the methodsetObject
above, except that it assumes a scale of zero.- Parameters:

data type and the JDBC driver does not support this data type- See Also:
Types
-
setObject
void setObject(int parameterIndex, Object x) throws SQLException
Sets the value of the designated parameter using the given object. The second parameter must be of type
Object
; therefore, thejava.lang
equivalent objects should be used for built-in types.The JDBC specification specifies a standard mapping from Java
Object
types to SQL types. The given argument will be converted to the corresponding SQL type before being sent to the database.Note that this method may be used to pass datatabase- specific abstract data types, by using a driver-specific Java type. If the object is of a class implementing the interface
SQLData
, the JDBC driver should call the methodSQLData.writeSQL
to write it to the SQL data stream. If, on the other hand, the object is of a class implementingRef
,Blob
,Clob
,NClob
,Struct
,java.net.URL
,RowId
,SQLXML
orArray
, the driver should pass it to the database as a value of the corresponding SQL type.Note: Not all databases allow for a non-typed Null to be sent to the backend. For maximum portability, the
setNull
or thesetObject(int parameterIndex, Object x, int sqlType)
method should be used instead ofsetObject(int parameterIndex, Object x)
.Note: This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.
- Parameters:
parameterIndex
- the first parameter is 1, the second is 2, ...x
- the object containing the input parameter value- Throws:
SQLException
- if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs; this method is called on a closedPreparedStatement
or the type of the given object is ambiguous
-
execute
boolean execute() throws SQLException
Executes the SQL statement in thisPreparedStatement
object, which may be any kind of SQL statement. Some prepared statements return multiple results; theexecute
method handles these complex statements as well as the simpler form of statements handled by the methodsexecuteQuery
andexecuteUpdate
.The
execute
method returns aboolean
to indicate the form of the first result. You must call either the methodgetResultSet
orgetUpdateCount
to retrieve the result; you must callgetMoreResults
to move to any subsequent result(s).- Returns:
true
if the first result is aResultSet
object;false
if the first result is an update count or there is no result- Throws:
SQLException
- if a database access error occurs; this method is called on a closedPreparedStatement
or an argument is supplied to this methodSQLTimeoutException
- when the driver has determined that the timeout value that was specified by thesetQueryTimeout
method has been exceeded and has at least attempted to cancel the currently runningStatement
- See Also:

Statement.addBatch(java.lang.String)
-
setCharacterStream
void setCharacterStream(int parameterIndex, Reader reader, int length) throws SQLException
Sets the designated parameter to the givenReader
object, which is the given number of characters long. When a very large UNICODE value is input to aLONGVARCHAR
parameter, it may be more practical to send it via ajava.io.Reader
object. The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from UNICODE to the database char format.Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.
- Parameters:
parameterIndex
- the first parameter is 1, the second is 2, ...reader
- thejava.io.Reader
object that contains the Unicode datalength

- 1.2
-
getMetaData
ResultSetMetaData getMetaData() throws SQLException
Retrieves aResultSetMetaData
object that contains information about the columns of theResultSet
object that will be returned when thisPreparedStatement
object is executed.Because a
PreparedStatement
object is precompiled, it is possible to know about theResultSet
object that it will return without having to execute it. Consequently, it is possible to invoke the methodgetMetaData
on aPreparedStatement
object rather than waiting to execute it and then invoking theResultSet.getMetaData
method on theResultSet
object that is returned.NOTE: Using this method may be expensive for some drivers due to the lack of underlying DBMS support.
- Returns:
- the description of a
ResultSet
object's columns ornull
if the driver cannot return aResultSetMetaData
object - Throws:
SQLException
- if a database access error occurs or this method is called on a closedPreparedStatement
SQLFeatureNotSupportedException

value, using the givenCalendar
object. The driver uses theCalendar
object to construct an SQLDATE
value, which the driver then sends to the database. With aCalendar
object, the driver can calculate the date taking into account a custom timezone. If noCalendar
object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.- Parameters:
parameterIndex
- the first parameter is 1, the second is 2, ...x

setNull
void setNull(int parameterIndex, int sqlType, String typeName) throws SQLException
Sets the designated parameter to SQLNULL
. This version of the methodsetNull
should be used for user-defined types and REF type parameters. Examples of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-defined and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the given typeName is ignored.
- Parameters:
parameterIndex
- the first parameter is 1, the second is 2, ...sqlType
- a value fromjava.sql.Types
typeName
- the fully-qualified name of an SQL user-defined type; ignored if the parameter is not a user-defined type or REF- Throws:

setObject
void setObject(int parameterIndex, Object x, int targetSqlType, int scaleOrLength) throws SQLException
Sets the value of the designated parameter with the given object. The second argument must be an object type; for integral values, the
java.lang
equivalent objects should be used. If the second argument is anInputStream
then the stream must contain the number of bytes specified by scaleOrLength. If the second argument is aReader
then the reader must contain the number of characters specified by scaleOrLength. If these conditions are not true the driver will generate aSQLException
when the prepared statement is executed.The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface
SQLData
), the JDBC driver should call the methodSQLData.writeSQL
to write it to the SQL data stream. If, on the other hand, the object is of a class implementingRef
,Blob
,Clob
